My Korean wife & I visited her parents after we got married. My father-in-law offered me a shot of Soju, which I accepted. He offered another, which I accepted. I was on an empty stomach and not much of a drinker to start with and was feeling the effects. He offered me another, and I did not want to give offence, so I accepted it. Two more and I was starting to get pretty drunk. I asked my wife if I could decline without offending him and she said by all means, and in fact during this time he had asked her if I was an alcoholic, and why did I keep drinking all this soju, as it was only lunchtime? As it turned out he didn't want to offend me by not offering me more.
